Except that it doesn't make sense.

- I am assuming that the calculations involved treating light from the star as a classical light wave passing through a classical medium with time-varying refractive index, so no quantum effects need to be calculated.At some point in the system, you need to generate an electrical signal representative of the wavefront distortion. This involves a photon-electron converter (usually a CCD), which, like all photon detectors, employs quantum phenomena!
Quote from: alancalverd on Today at 09:21:10Detection efficiency isn't relevant - you have to integrate over a reasonable period to determine intensity.
If we initially detect intensity I1 at pixel A and 0 at A + 1, then subsequently detect I A < I1 and I A+1 > 0, we can infer.......
..... that the pixels just don't click with 100% effectiveness? that the air changed its density locally? or maybe that the source image was rotating.
5) Has it Ever happened that a Coin was tossed & it Disappeared into thin air & never landed.Eddington said that the student of physics must become accustomed to having his common sense violated five times before breakfast, and if he disappeared through the floor and rematerialised in the cellar, he would not consider it mysterious but merely a lucky observation of a very rare phenomenon.
I just did a quick experiment by rapidly waving a fridge magnet across my heart and also my head. Nothing happenedBeware the onesided correlation!
Morocco gets a fair bit of the Sun.Only during daylight hours, which are pretty much the same as the UK. and if you covered Morocco with solar panels, the sensible next step would be to move all your manufacturing industry to Morocco.
Tidal Wave energy has Potential.There have been attempts to harness tidal and wave power for several centuries. Some tidal mills were reasonably successful at grinding corn but AFAIK there are very few suitable locations for tidal generation of electricity and those that aren't commercial ports (not a good idea to erect a dam across Southampton) would require flooding of vast areas of farmland to produce a useful amount of power. Wave power is less predictable than wind and involves enormous quantities of moving machinery being tethered in a hostile environment - again, very little output from a huge number of failed projects over the last 100 years.
